Enumeration of living aerobic micro-organisms in bull sperm

This document establishes a standardized procedure for determining the concentration of viable aerobic microorganisms within semen samples. It provides detailed guidelines for sample collection, preparation, and incubation to ensure consistent and reproducible results across different laboratories. The methodology outlines specific media formulations, incubation temperatures, and durations required to accurately quantify microbial counts. By adhering to these technical specifications, testing facilities can maintain high quality control in the assessment of semen sterility. The standard covers essential steps from dilution techniques to colony enumeration methods, ensuring that measurements are performed under controlled conditions. It serves as a reference for laboratory personnel conducting microbiological analysis in reproductive medicine contexts. The protocol aims to minimize variability between tests and provides a unified approach for evaluating microbial presence. This framework supports quality assurance processes without imposing additional requirements beyond the defined technical steps. Adherence to this methodology facilitates reliable data comparison and contributes to consistent diagnostic outcomes in relevant medical and research environments.
